MTP Kit

Generic

Mifepristone + Misoprostol

 

Indications

This kit is suitable for early menstrual regulation (MR)/termination of pregnancy within 9 weeks (63 days) of pregnancy.

 

Pharmacology

Mifepristone: Mifepristone is a synthetic steroid with anti-progesterone activity, derived from a competitive interaction with progesterone at the progesterone receptor site. Based on the study of different oral doses in various animals, the compound can inhibit endogenous or exogenous progesterone activity and menstrual regulation (MR) results. During pregnancy, the compound sensitizes the myometrium to the contraction-inducing activity of prostaglandins.

 Misoprostol: Misoprostol is a synthetic prostaglandin E1 analog. It causes the myometrium to contract by interacting with specific receptors on the myometrial cells. This interaction causes a change in calcium concentration, which initiates muscle contraction. By interacting with prostaglandin receptors, misoprostol causes softening of the cervix and contractions of the uterus, thus expelling the contents of the uterus.

 

Dosage & Administration

his can only be prescribed by qualified medical professionals who are able to assess the gestational age of an embryo and to diagnose ectopic pregnancies. The qualified medical professionals must also be able to provide surgical Intervention/MVA (Manual Vaccum Aspiration) in cases of incomplete abortion or severe bleeding or have made plans to provide such care through others and be able to assure patient access to medical facilities equipped to provide blood transfusions and resuscitation, if necessary.

Day 1 (First visit): Mifepristone administration: One tablet of Mifepristone (200 mg) is taken in a single oral dose under the supervision of a qualified medical professional in a clinic, medical office or hospital.

This visit is very important to confirm by clinical examination or ultrasonographic scan that a complete termination of pregnancy has occurred.

Patients who have an ongoing pregnancy at this visit have a risk of fetal malformation resulting from the treatment. Surgical termination/MVA is recommended to manage Menstrual Regulation (MR)/termination of pregnancy failures.
